Abstract

This study presents a test of the long short term memory (LSTM) algorithm on traffic prediction with multi edge server and cloud server architectures. IoT sensors located on the roadside such as cameras and location data on each driver are used and stored in the data center. When a driver sends a travel time request to a nearby edge server, traffic predictions will be made on the edge server or cloud server. Server selection is made based on the destination location of the driver's request. If the destination is in the edge server area, traffic predictions are made on the edge server. However, if the destination is in the cloud server area, traffic predictions are made on the cloud server. Then to predict traffic traffic is done with LSTM. following modeling is made with a density of 128 and a density of 256. By learning from previous traffic, LSTM with a greater density gets a proportion of errors, namely RMSE 10.78%, MAE 8.24%, and MAPE 19.87%.

Abstract

Makassar City is the fourth-largest city in Indonesia and the largest in Eastern Indonesia with an area of 175.77 square km and a population of ±1.5 people in 2019, divided into 15 districts and 143 sub-districts. Uneven population density in each sub-district has an impact on the emergence of social problems in society such as: unhealthy environment, chaotic building management, population registration information that is not updated. To overcome this problem, it is necessary to have population info graphics that show the population, age of the population, education, etc. With info graphic data on the population of Makassar city that can be accessed online, people looking for data can use it as a reference. To achieve the objectives of this research, the K-means algorithm method is used to divide observations into K clusters where each observation is a member of the cluster with the closest average value, through an iterative process until the grouping converges. The K-means algorithm can be used on population data. For example, the grouping of population data is divided into three clusters, namely (cluster 1) dense, (cluster 2) medium and (cluster 3) not dense. The results obtained show that five districts: Mariso, Mamajang, Makassar, Bontoala and Tallo are the districts with the densest populations.

Abstract

Water absorption testing through soil percolation test is mostly handled manually. During the testing process, it still requires many people to supervise it, and the reading error rate is still high. Therefore, a measuring instrument that works automatically is needed that can more specifically read the rate of water absorption into the soil accurately. In this final project, the tool is made using Arduino Mega, HC-SR04 ultrasonic sensor, 128x64 LCD, buzzer, NEO6MV2 GPS Module, RTC (Real Time Clock), push button, and Lithium-Ion Battery. The result of this final project is a soil permeability measuring instrument that can accurately measure the rate of water infiltration. Based on the results of design, testing and analysis of the design results, a soil permeability measuring instrument is obtained that can properly measure the rate of water infiltration

Abstract

Distribution transformers are devices designed to transmit electrical energy from the power source to consumers. The loading percentage on distribution transformers must not exceed the health index standard of 80% of their capacity, in accordance with the regulations of PT.PLN (Persero) as stated in directorate circular Number: 0017.E/DIR/2014. In addition to the loading percentage, the voltage variation in electrical distribution must comply with the specified limits of +5% and -10% from the nominal voltage as per SPLN No.1 of 1995. This research was conducted to analyze one of the distribution transformers that experienced overload, leading to a voltage drop in the electrical network system, necessitating appropriate measures to address the issue. The load forecasting for determining the capacity and lifespan of transformers is conducted using the Least Square method. Data from 2022 shows that the distribution transformer with the code "gardu 610.OK," with a capacity of 100 kV in the Walmas feeder at PT. PLN (Persero) ULP Palopo Kota, experienced an excessive load of up to 85.67%, resulting in a voltage drop of up to 18.2%. The research findings indicate that the installation of an additional transformer can reduce the loading percentage to 52.95% and improve the voltage drop percentage to 4.9% in the first quarter of 2023.
